BARREL-COMPRESSING MACHINE.

SPECIFICATION forming part of Letters Patent No. 439,273, dated October 28, 1890.

Application filed May 25, 1889.

.To aZZ whom it may concern.-

Be it known that I, IVIILTON A. HAMILTON,

a citizen of the United States, residing at Detroit, county of Wayne, State of Michigan,

have invented a certain new and useful Improvement in Barrel-Compressing Machines; and I declare the following to be a full, clear,

and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, ref

kegs made from woven fabric and for compressing said fabric upon the heads for hooping or otherwise securing the compressed fabric with the heads, all as more fully hereinafter specified, pointed out in the claims, and illustrated in the accompanying drawings, in which- 4 Figure l is a plan view of the device embodying my invention, showing the rim of the friction-pulley broken away. Fig. 2 is a side elevation of the same. Fig. 3 illustrates modifications of my invention. Fig. at is a sectional view on the line a: m, Fig. 1.

In the construction of certain devices from woven fabric and otherwise a very satisfactory and effi cient method of securing the head in place in the body of the package, as in a barrel or keg, is to compress the extremities of the said body upon the periphery of the said head, in which compressed position the body is held firmly upon the head by a hoop or other means. My invention is intended to secure this compression, and is carried out as follows:

A represents any suitable support.

13 is a driving-shaft properly journaled on said support and provided, preferably, with a friction hub or head B.

B is the driving-pulley.

C is a rotatable shaft suitably journaled on the support and provided with right and left hand screw-threads, as indicated at c c, and also with sliding or traveling nuts 0' 0 constructed or provided with a fastening device to engage the ends, respectively, of a rope D, as shown at c 0 $eria1 No. 312,050. on model.)

E is a friction-pulley on the screw-threaded shaft 0, preferably constructed with a broadened rim E and a central hub E and friction-rim E The friction-head B is so arranged as to be moyed laterally to form contact either with the rim E or with the rim E as may be desired. To accomplish this purpose, an operating-lever F is suitably engaged therewith,

whereby said head may be moved readily at the will of the operator. tion said head may rotate between said rim Eaud the rim E out of contact with either. To restorethe said head to this normal position after being thrown in either direction by the operator, any suitable device may be employed-as, for instance, the lever may be weighted, as shown at F, to accomplish this result. V

G denotes a barrel or keg, about which the rope D is shown engaged in a proper manner therewith, thereby compressing the end of the body of the barrel upon the head very firmly. The hoop G is then applied to hold the compression secured, when the rope may be relaxed by rotating the shaft 0 in the op posite direction, and thereby causing the nuts to travel toward each other, slacking up the rope. Itwill be seen that greater power is desired to secure the compression than to slacken the rope; also, that the latter operation may be accomplished more quickly than the former. To secure these respective results, the friction-head B is forced against the rim E to pull the rope tight-upon the barrel, the circumference of the rim adding to the powersecuredpvhile the frictional contact secured provides for the slipping of the head B thereupon when too great tension is secured, preventingliability of breakage. By throwing the friction-head upon the rim E In its normal posithe same being of small diameter, the shaft 0 is reversed swiftly to slacken the rope and run' the nuts into proper position for a new operation. The head B being restored to its normal position, the driving-shaft may continue to rotate continuously in the same direction. As the said head is first moved in one direction against the rim E and in another direction against the rim E it is clear that the shaft C will be rotated thereby in opposite directions.

Thedevice is very simple and inexpensive and of great efficiency.

The construction of the friction-pulley E wil h rims E and E makes it a double frictionpulley. The special benefits of a friction device to control the operation of the shaft 0 might be secured by other arrangements and constructions of the friction mechanism within the scope of my invention.

WhileI have described the shaft 0 as constructed with right and left hand screwthreads, such a construction is not indispensable within the scope of my invention, as it might be threaded in a single direction and the rope passed about a pulley H, as shown in Fig. 3. So, also, it is not essential to my invention that the shaft 0 be provided with two traveling nuts, as one end of the cord might be secured to apermanent or fixed fast-' ening. I desire to so construct the pitch of the threads upon said shaft that the degree of pitch will hold the compression of the fabric in required subjection when the lever is released without the employment of any additional device for this purpose. Both ends of the rope might be engaged with a single nut, as indicated in Fig. 3, one end being led about the pulley H, said pulley serving to reverse the direction of the movement of the extremity of said rope. In full lines the rope is shown in Fig. 3 as engaged with the two nuts 0 C both traveling in the same direction, the pulley reversing the direction of the rope at one extremity. The dotted lines show the extremity of the rope passed about the pulley carried to the nut C both extremities of the rope being thus engaged therewith.

hat I claim as my invention is 1. In a barrelcompressing machine, the combination,with a rotatable screw-threaded shaft, of one or more nuts traveling in the same direction upon said shaft,a rope having its extremities engaged with said nut or nuts, and a pulley upon which the bight of said rope is engaged to reverse the direction of one end of said rope, substantially as set forth.

2. The combination, with a support, of a screw-threaded shaft journaled thereupon, a f riction-pnlleylocated upon said shaft and provided with rims E and E one of greater circumference than the other, whereby the said shaft may be rotated in one direction faster than in the other, a drivin -shaft provided with a friction-head to engage said rims at the will of the operator, one or more traveling nuts located upon the screw-threaded shaft, and a rope connected to said nut or nuts, substantially as set forth.

In testimony whereof I sign this specification in the presence of two witnesses.

MILTON A. HAMILTON.
